Unplug the battery following the guide, then with nothing connected press the power button holding it for a good 10 secs so we fully discharge the logic board, now plug in the MagSafe, turn on the system, it should start, shut it down and plug back in the battery, leave the system off, let it charge for the night (good 10 hrs). Then take a fresh snap of CoconutBattery.

@Joe Perry - Well at this point we need to see what the old battery is telling us, As I’m starting to think the charging logic on the logic board is damaged. There are a pair of resistors which are use to compare the voltages which I’m suspecting are damaged.
Lets carefully unplug the new battery and carefully plug in your old just so we can get the MagSafe charger plugged in and get a CoconutBattery output after giving it a good 1/2 hour of charge.
If that is also showing no charge then that confirms the logic is damaged if on the other hand it is showing the battery is taking the charge then the battery micro-controller is messed up.
As far as the Age value its just the calculation of the days between when the battery was made and the day you snapped the pic. It has little bearing on what we are dealing with here.

Don’t need any pics or vid at this point.
